I also don't quite know how to create the rounded corners.
我也不太知道如何创建圆角。

Use a normal blue border, a medium border-radius, and a blue box-shadowwith position 0 0.
使用普通蓝色border、中border-radius色box-shadow和带位置的蓝色0 0。

SLaks hit the nail on the head but you might want to look over the changes for inputs in CSS3 in general. Rounded corners and box-shadow are both new features in CSS3 and will let you do exactly what you're looking for. One of my personal favorite links for CSS3/HTML5 is http://diveintohtml5.ep.io/.
SLaks 一针见血，但您可能希望查看 CSS3 中输入的总体变化。圆角和框阴影都是 CSS3 中的新功能，可以让您完全按照自己的意愿行事。我个人最喜欢的 CSS3/HTML5 链接之一是http://diveintohtml5.ep.io/。

outline:none;
border: 1px solid #4195fc;
/* create a BIG glow */
box-shadow: 0px 0px 14px #4195fc;
-moz-box-shadow: 0px 0px 14px #4195fc;
-webkit-box-shadow: 0px 0px 14px #4195fc;
}?

Below is the code that Bootstrap uses. Colors are bit different but the concept is same. This is if you are using LESS to compile CSS:
下面是 Bootstrap 使用的代码。颜色有点不同，但概念是一样的。这是如果您使用 LESS 来编译 CSS：
// Form control focus state
//
// Generate a customized focus state and for any input with the specified color,
// which defaults to the `@input-focus-border` variable.
//
// We highly encourage you to not customize the default value, but instead use
// this to tweak colors on an as-needed basis. This aesthetic change is based on
// WebKit's default styles, but applicable to a wider range of browsers. Its
// usability and accessibility should be taken into account with any change.
//
// Example usage: change the default blue border and shadow to white for better
// contrast against a dark gray background.
.form-control-focus(@color: @input-border-focus) {
@color-rgba: rgba(red(@color), green(@color), blue(@color), .6);
&:focus {
border-color: @color;
outline: 0;
.box-shadow(~"inset 0 1px 1px rgba(0,0,0,.075), 0 0 8px @{color-rgba}");
}
}
If you are not using LESS then here's the compiled version:
如果您没有使用 LESS，那么这里是编译版本：
.form-control:focus {
border-color: #66afe9;
outline: 0;
-webkit-box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075), 0 0 8px rgba(102, 175, 233, 0.6);
box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075), 0 0 8px rgba(102, 175, 233, 0.6);
}
